Cards that looks weak on paper, but isnt?

Do you know any cards here that looks weak on paper, but are actually pretty good/great?

for me, Petra is the 1 card that looks weak on paper but are good . i mean 7/5 for a 4*? looks pretty weak. but the truth is that her sob shuts down annoying attack manipulation clans, and then puts the opponents down to 1 pill less most of the time

Mona is pretty much the best 3* in Montana while Piranas have a lot of really good 5* to choose from. Also Sliman is a common card. Doesn't mean Sliman is bad, he goes well with all the 4 damage cards that Piranas have.

Elke is not useless, she can mess up the opponent strategy, and if use on attack, will make the opponent underpill. I've fought many people that turn defensive when I threw her out and messed their pill count. Especially those who open their fight by heavy pilling, making it easier for me to predict what they'll do.
